Well, now I'm confused. Greenboard was recommended to me by a professional
tile maker here in town so that's what I've used with good success. My
husband now informs me that greenboard is less absorbent than regular
wallboard (sheetrock)- that's why it's used in bathrooms. The fact that
sheetrock absorbs more water may not be a bad thing for our purposes but
probably makes it less durable. I say, use whatever works best.
